打字稿-开玩笑-tsconfig：在Resolver.resolveModulenode_modules / jest-resolve / build / index.js：259：17找不到模块'.. / ...'

问题描述

我正在使用：

• vscode v1.49.2
• 玩笑跑步者v0.4.24扩展
• 节点：14.10.1
• win10：64位

"devDependencies": {
        "@types/jest": "24.0.23","@types/jest-when": "2.7.0","jest": "24.9.0","jest-cli": "24.9.0","jest-coverage-badges": "1.1.2","jest-create-mock-instance": "1.1.0","jest-html-reporter": "^3.1.2","jest-jenkins-reporter": "1.0.2","jest-junit-reporter": "1.1.0","jest-when": "2.7.0","typescript": "^3.8.3"
    },

问题：开玩笑无法解析相对路径

从'command.test.ts'中找不到模块'../../ common / utility / json.utility'

1 |从'../../common/utility/json.utility'导入{JsonUtility}; | ^

在Resolver.resolveModule（node_modules / jest-resolve / build / index.js：259：17） 在对象。 （test / command / poll / command.test.ts：1：1）

我的配置：

** jest.config.js：**详细信息

module.exports = {
    verbose: true,transform: {
        '^.+\\.tsx?$': 'ts-jest'
    },testEnvironment: 'node',testRegex: '(/test/.*|(\\.|/)(test|spec))(\\.it)?\\.(jsx?|tsx?)$',testPathIgnorePatterns: ['/coverage','/lib','/test/fixture'],testResultsProcessor: './node_modules/jest-junit-reporter',modulefileExtensions: ['ts','tsx','js','jsx','json','node'],coverageThreshold: {
        global: {
            branches: 15,// 80
            functions: 15,// 80
            lines: 15,// 80
            statements: 0 // 20
        }
    },collectCoverageFrom: ['src/**/*.ts','!src/index.ts'],coverageReporters: ['json-summary','text','lcov']
};

tsconfig.json： tsconfig的详细信息

{
    "compilerOptions": {
        "target": "es6","module": "commonjs","lib": [
            "es6","esnext"
        ],"declaration": true,"sourceMap": true,"outDir": "lib","rootDirs": [

    },"exclude": [
        "typedoc","**/*.d.ts","node_modules","**/node_modules/*","lib"
    ]
}

最好的问候

解决方法

您可能想开玩笑地配置模块路径：https://jestjs.io/docs/en/configuration#modulepaths-arraystring

类似的东西：

module.exports = {
    verbose: true,transform: {
        '^.+\\.tsx?$': 'ts-jest'
    },testEnvironment: 'node',testRegex: '(/test/.*|(\\.|/)(test|spec))(\\.it)?\\.(jsx?|tsx?)$',testPathIgnorePatterns: ['/coverage','/lib','/test/fixture'],testResultsProcessor: './node_modules/jest-junit-reporter',moduleFileExtensions: ['ts','tsx','js','jsx','json','node'],coverageThreshold: {
        global: {
            branches: 15,// 80
            functions: 15,// 80
            lines: 15,// 80
            statements: 0 // 20
        }
    },collectCoverageFrom: ['src/**/*.ts','!src/index.ts'],coverageReporters: ['json-summary','text','lcov'],modulePaths: [ // Add your paths here
        "<rootDir>/src/"
    ],};
